INTRODUCTION

Congratulations on your purchase of the 2:8 DVI Distribution Amplifi er. The 2:8 DVI distri-
bution amplifi er is an innovative solution for anyone with more complex computer system
requirements, like studios and presentation venues where multi-viewing is essential. The
2:8 DVI distribution amplifi er accommodates various system scenarios. Most commonly,
two video sources (either DVI-equipped computer, DVD player or satellite set top box)
are connected to the distribution amplifi er on one side. On the output side, eight video
outputs are available to be used in part or in full. Once the unit is connected and powered,
each source can be routed to multiple displays. All DVI displays are driven by the two DVI
sources with each source or computer capable of driving eight displays at one time. For
home theater applications, the unit is HDCP (high defi nition content protection) compliant,
making it effective for use with all DVI displays.

How it works:

Gefen’s 2:8 DVI distribution amplifi er is an expandable distribution hub that sends the
same DVI graphics source to eight DVI based digital screens (fl at panels or projectors). It
is a fl exible solution that accommodates multiple DVI displays. Y ou can switch from source
one and two via the RMT-2IR remote control, as well as switching using the RS-232 serial
communications port located on the rear panel.

The Gefen 2:8 DVI distribution amplifi er is connected with a DVI (male to male) cable from
the DVI graphic source to the distribution amplifi er input. There are eight DVI outputs in
each module. DVI output one is the primary connection and is used for the main display.
DVI output 2 thru 8 follow the main display. The 2:8 DVI distribution amplifi ers is using a
unique DVI Bus™ technology to connect multiple amplifi ers without sacrifi cing a DVI output
connection. The ninth output is an expansion output used to daisy chain an additional 2:8
DVI Distribution Amplifi er. The 2:8 DVI Distribution Amplifi er is expandable to 256 outputs
(32 DVI DA’s).
